多种权重下我国高铁与民航空间分布特征

The Spatial Distribution Characteristics of China's High Speed Railway and Civil Aviation under Multiple Weights

从全国视角出发,对我国内地高铁和民航基础设施的空间分布特征及其与经济发展、人口分布间的联系进行分析。考虑邻接关系、距离邻近度、经济邻近度等因素,构建四种空间权重矩阵,通过全局莫兰指数对我国31个省级行政区高铁和民航基础设施以及经济和人口等指标的空间相关性进行对比研究,并利用局部莫兰指数对区域层面表现出的空间聚集性进行具体分析。研究发现我国高铁和民航设施分布存在显著的空间聚集现象和互补现象;高铁建设与地区经济发展存在影响关系且发展趋势相同;机场建设与人口分布相协调,并且在人均指标方面相对较均衡。

From a national perspective, the spatial distribution characteristics of high speed railway and civil aviation infrastructure in China's mainland and their relationship with economic development and population distribution were analyzed. Taking into account factors such as adjacency, distance proximity, and economic proximity, four spatial weight matrices are constructed. The global Moran index is used to compare and study the spatial correlation of high-speed rail and civil aviation infrastructure, as well as economic and population indicators in 31 provinciallevel administrative regions in China. The local Moran index is also used to analyze the spatial clustering exhibited at the regional level. Research has found significant spatial clustering and complementarity in the distribution of high speed railway and civil aviation facilities in China;There is an impact relationship between high speed railway construction and regional economic development, and the development trend is the same;Airport construction is coordinated with population distribution and relatively balanced in terms of per capita indicators.
